Hi,
1. Please open file CuteSoft_Client\CuteEditor\Languages\nl-NL.xml and find section below, remove the : from the text setting will fix this problem.
<resource name="Find what">Zoeken naar:</resource>
2. This message is hard code in js fileCuteSoft_Client\CuteEditor\Scripts\Dialog\Dialog_Find.js, it is not based on the language file, so if you want to change this text, you need to change it in this js file directly. you can search keyword below to find the message from the js file.
Finished Searching the document. Would you like to start again from the top?
3. Which search function you mean? Can you explain it in detail?
4. You can custom the spell checker pop up message from file \CuteSoft_Client\CuteEditor\Scripts\spell.js, same as question 2.
Regards,
Ken
